ibatis分页实现主要步骤：
a. 创建Page类。
b.创建bean类，并继承Page类。
b. 在dao层，定义两个方法。并实现该方法。
c. 在业务层，同样定义两个方法。并实现它。
d. 在配置文件中注入有关的page类。并设置相应的get和set方法。
e. 在action中调用有关的方法。
f.进行配置文件的设置。


详细步骤：
1.        Page类
package com.exeerp.sm.bean;
public class Page
{
        private int pagesize;//单页记录
        private int currentpage = 1;//当前页面
        private int countdate;//总记录数
        private int lastPage;
        private int nextPage;
        private int countPage;
        public int getCurrentpage() 
        {
                return currentpage;
        }
        public void setCurrentpage(int currentpage) 
        {
                
                if(currentpage>getCountpage())
                {
                        this.currentpage = getCountpage();
                }else {
                        if(currentpage < 1)
                        {
                                this.currentpage = 1;
                        }
                        else
                        {
                                this.currentpage = currentpage;
                        }
                }
        }
        public int getPagesize() {
                return pagesize;
        }
        public void setPagesize(int pagesize) {
                this.pagesize = pagesize;
        }
        public int getCountdate() 
        {
                return countdate;
        }
        public void setCountdate(int countdate) 
        {
                this.countdate = countdate;
        }
        //由记录数设定有关的页面数。
        public int getCountpage() 
        {
                int i = this.countdate / this.pagesize;
                if((this.countdate % this.pagesize)!=0)
                {
                        i+=1;
                }
                return i;
        }
        public int getLastPage()
        {
                return this.getCurrentpage()-1;
        }
        public int getNextPage()
        {        
                return this.getCurrentpage()+1;
        }
        //给ibatis用数据
        public int getCurrent() 
        {
                return (this.currentpage-1)*pagesize;
        }
        public int getNext() {
                return this.currentpage*pagesize;
        }
        public int getCountPage() {
                return countPage;
        }
        public void setCountPage(int countPage) {
                this.countPage = countPage;
        }
        public void setLastPage(int lastPage) {
                this.lastPage = lastPage;
        }
        public void setNextPage(int nextPage) {
                this.nextPage = nextPage;
        }

}

2.        创建bean类，并继承Page类
  package com.exeerp.sm.bean;
import com.exeerp.sm.bean.Page;
import java.util.*;

public class Flow extends Page
{
   //审批编号
   private String flowId;
   //审批名称
   private String flowName;
   //审批路径
    private String flowUrl;
    //审批描述
   private String flowClass;
public String getFlowId() {
        return flowId;
}
public void setFlowId(String flowId) {
        this.flowId = flowId;
}
public String getFlowName() {
        return flowName;
}
public void setFlowName(String flowName) {
        this.flowName = flowName;
}
public String getFlowUrl() {
        return flowUrl;
}
public void setFlowUrl(String flowUrl) {
        this.flowUrl = flowUrl;
}
public String getFlowClass() {
        return flowClass;
}
public void setFlowClass(String flowClass) {
        this.flowClass = flowClass;
}



   
}


3.在dao层，定义两个方法,并实现该方法



  dao层接口
package com.exeerp.sm.dao;
import java.util.List;
import com.exeerp.pub.exception.BizException;
import com.exeerp.pub.exception.DaoException;
import com.exeerp.sm.bean.Flow;;
public interface FlowDAO
{
        public List getPageList(Object obj)throws BizException, DaoException;
        public int getCountSize(Object obj)throws BizException, DaoException;

}
  dao层接口实现
package com.exeerp.sm.dao.impl;
import java.util.*;
import com.exeerp.sm.bean.Flow;
import com.exeerp.sm.dao.FlowDAO;
import com.exeerp.pub.dao.AbstractBaseDAO;
import com.exeerp.pub.exception.BizException;
import com.exeerp.pub.exception.DaoException;
import org.springframework.orm.ibatis.support.SqlMapClientDaoSupport;

public class FlowDAOImpl extends AbstractBaseDAO implements FlowDAO
{
  public List getPageList(Object obj)throws BizException, DaoException
        {
                return this.getSqlMapClientTemplate().queryForList("select-Flow", obj);
        }
        public int getCountSize(Object obj)throws BizException, DaoException
        {
                
                return  (Integer)this.getSqlMapClientTemplate().queryForObject("selectcountsize-Flow");
        }
}


4.在业务层，同样定义两个方法。并实现它。

package com.exeerp.sm.biz;
import java.util.List;
import com.exeerp.sm.bean.Flow;
import com.exeerp.pub.exception.BizException;
import com.exeerp.pub.exception.DaoException;

public interface FlowManager 
{

         public List<Flow> findAll(Object obj)throws BizException,DaoException,Exception;
         public int getCountSize(Object obj)throws BizException,DaoException;
}
业务层实现类
package com.exeerp.sm.biz.impl;
import java.util.List;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.BeanFactory;
org.springframework.context.support.ClassPathXmlApplicationContext;
import com.exeerp.sm.dao.*;
import com.exeerp.sm.bean.Flow;
import com.exeerp.sm.biz.*;
import com.exeerp.pub.exception.BizException;
import com.exeerp.pub.exception.DaoException;
import com.exeerp.pub.util.ExceptionMessage;
import java.util.*;

public class FlowManagerImpl implements FlowManager 
{
        static Logger logger = Logger.getLogger(FlowManagerImpl.class);
        private FlowDAO flowDao;

public int getCountSize(Object obj)throws BizException,DaoException
         {
                 return flowDao.getCountSize(obj);
         }
           public List<Flow> findAll(Object obj)throws BizException,DaoException,Exception
{
      List<Flow> all=new ArrayList();
                 try
                 {                        
                     //all=flowDao.findAll(obj);
                     all = flowDao.getPageList(obj);
                         if(all!=null)
                         {
                                 System.out.println("-----FlowManagerImpl.findAll()"+all);
                         }
                 }
                 catch(Exception ex)
                 {
                         ex.printStackTrace();
                 
                 }
                 return all;
}
          
        public FlowDAO getFlowDao() {
                return flowDao;
        }
        public void setFlowDao(FlowDAO flowDao) {
                this.flowDao = flowDao;
        }
}



Action类：
package com.exeerp.sm.ctrl;
import java.util.List;
import org.apache.log4j.Logger;
import org.springframework.beans.factory.BeanFactory;
import org.springframework.context.support.ClassPathXmlApplicationContext;
import com.exeerp.sm.biz.FlowManager;
import com.exeerp.sm.dao.*;
import com.exeerp.pub.action.BaseAction;
import com.exeerp.pub.exception.BizException;
import com.exeerp.pub.exception.DaoException;
import com.exeerp.pub.util.ExceptionMessage;
import com.exeerp.sm.bean.*;
import org.apache.struts2.ServletActionContext;//引出request对象
import java.io.*;

public class FlowManagerAction extends BaseAction 
{
        //记录日志信息
        static Logger logger = Logger.getLogger(FlowManagerAction.class);
   //引用的业务层的对象，
        private FlowManager flowManager;//
        //引用审批的bean对象
    private Flow flow;
    private List<Flow> all;
    private final static int pagesize = 10; 
        private int countdate;//总记录
        private Page page;//在action中注入该对象
    public List<Flow> getAll() 
    {
                return all;
        }
        public void setAll(List<Flow> all) 
        {
                this.all = all;
        }
    public FlowManager getFlowManager() {
                return flowManager;
        }
        public void setFlowManager(FlowManager flowManager) {
                this.flowManager = flowManager;
        }
        public Flow getFlow() {
                return flow;
        }
        public void setFlow(Flow flow) {
                this.flow = flow;
        }
        public int getCountdate() {
                return countdate;
        }
        public void setCountdate(int countdate) {
                this.countdate = countdate;
        }
        public Page getPage() {
                return page;
        }
        public void setPage(Page page) {
                this.page = page;
        }
        public static int getPagesize() {
                return pagesize;
        }
     
    public String findAll()throws Exception
    {
            String result=this.ERROR;
            try
            {   
                    //查询并获取该记录数
                    countdate = flowManager.getCountSize(new Flow());
                        flow.setPagesize(10);
                        flow.setCountdate(countdate);
                all=flowManager.findAll(flow);
                    if(all.size()>0)
                {
                        result=this.SUCCESS;
                  //保存查找的对象到request
                        ServletActionContext.getRequest().setAttribute("all",all);
                }
            }
            catch (BizException e)//进行业务层异常的捕获
                {
                    e.printStackTrace()
                    ;
                        logger.error(e.getMessage());
                        this.setMessage(e.getMessage());
             result ="error";
                  }
               catch (DaoException e) //进行数据访问层异常的捕获
                  {
                       e.printStackTrace();
                        logger.error(e.getMessage());
                        this.setMessage(e.getMessage());
                  } 
                  catch (Exception e)//进行其他异常的捕获
                  {
                          e.printStackTrace();
                        logger.error(ExceptionMessage.getMessage("common.serverException"));
                        this.setMessage(e.getMessage());
                  } 
                  finally 
                  {
                         return result;
                  }
}

Spring的xml的配置：
<bean id="flow" class="com.exeerp.sm.bean.Flow"></bean>
<bean id="page" class="com.exeerp.sm.bean.Page"></bean>

        <bean id="app-FlowManagerAction" class="com.exeerp.sm.ctrl.FlowManagerAction" scope="prototype">
                <property name="flowManager" ref="flowManager"/>
                <property name="flow" ref="flow"/>
                <property name="page" ref="page"/>
        </bean>

Ibetis配置：
  <!-- 显示所有的审批信息 -->
  <select id="select-Flow" resultClass="hashmap" parameterClass="Flow">
     
                <![CDATA[
                select * from (
                        select ROWNUM r,t.* from (
                                select * from Pub_Flow ) t) 
                        where r > #current# and r <= #next#
             ]]>
           <!-- 显示时只要修改对应的表名即可 -->
              <!-- 注：t代表select * from Pub_Flow的字符集
                    t.* 代表他t下的所有字符集
                    ROWNUM ：  行数
                   current next起止页
                  

    -->
  </select>
           <select id="selectcountsize-Flow" resultClass="Integer">
                <![CDATA[  select count(*) from Pub_Flow ]]>
        </select>
